Why does evolution always lead to more advanced species?

Evolution does not always lead to more advanced species. Evolution is simply a description of the way change occurs in biological creatures over many generations in order to better exploit a certain environment.

Evolution sometimes leads to progress, but it sometimes leads in the opposite direction.

For instance, the Texas blind salamander has lost his eyes after many generations of evolution due to the uselessness of eyes in the dark caves where he dwells. As reported by biologist David M. Hillis, these salamanders have successfully adapted to their environment by loosing their eyes. But going blind does not seem to be much in the way of progress from a global perspective.

How do flies walk on the ceiling?

Flies can walk upside down! They can do this because of their sticky feet.

A fly has foot pads that are covered in tacky glue.

To unstick their feet so they can walk anywhere, the fly uses tiny foot claws to push or twist themselves away.

How much water can a camel store in its hump?

Camels do not store water in their humps. Instead, camels use the humps to store energy-rich fat deposits. Many animals, including humans, use body fat as an energy storage.

Unique to a camel, however, is the fact that it stores the fat in a hump up on top instead of around the belly or limbs. It does this to stay cool. Fat has a natural tendency to insulate heat, acting like a blanket to bodies that are covered in fat. Being a hot-climate animal, a camel would waste energy trying to cool down if its fat were wrapped around its body.

Do blind people dream in visual images?

Yes, blind people do indeed dream in visual images. For people who were born with eyesight and then later went blind, it is not surprising that they experience visual sensations while dreaming.

Dreams are drawn from memories that are stored in the brain as well as from brain circuitry that is developed while experiencing the outside world. Therefore, even though a person who lost his vision may be currently blind, his brain is still able to draw on the visual memories and on the related brain circuits that were formed before he went blind. For this reason, he can dream in visual images.

Can a fire have a shadow?

Yes, you can form the shadow of a fire, but perhaps not for the reason that you are thinking. A shadow is formed any time part of a light beam is blocked or redirected. The shadow region is the region in the light beam where there is less light than in the rest of the beam. This dimmer region tends to take on the shape of the object that is blocking or redirecting some of the light, so we tend to think of a shadow as something that is cast or created by the intercepting object.

With this concept in mind, in order for a fire to have a shadow, the fire needs to somehow block or redirect part of another beam of light.

Why Babies have around 100 more bones than adults?

Babies have about 300 bones at birth, with cartilage between many of them. This extra flexibility helps them pass through the birth canal and also allows for rapid growth. With age, many of the bones fuse, leaving 206 bones that make up an average adult skeleton.

Why do we get headache when hungry?

Calories in food are a measurement of energy. Your body needs a consistent energy source in the form of food as fuel.

If you haven’t had anything to eat in a while, your blood sugar levels can drop. In response, your body releases hormones that signal your brain that you’re hungry. These same hormones may increase your blood pressure and tighten blood vessels in your body, triggering a headache.

Why do humans have an appendix even though it is unnecessary?

The human cecal appendix is not completely unnecessary. In humans, the appendix is a small, dead-end tube that connects to the colon near where the small intestines feeds into the large intestines.

Being a dead-end tube, the appendix can obviously not transport food and waste through the intestinal tract. Furthermore, many people have had their appendix removed and yet seem to suffer no symptoms at all from having no appendix.

This fact may seem to indicate that the appendix is useless; an abandoned evolutionary relict of some ancient predecessor. But the appendix turns out to not be completely useless.
